Transcript for Mother of Teenager Who Allegedly Bullied Rebecca Sedwick Is Arrested

And there is a new twist in the bullying case making headlines after a 12-year-old girl was bullied by classmates and took her own life. A tough talking sheriff decided to take action, he is leveling a brand new charge tonight. He has arrested the mother of an alleged bully. Why? Abc's matt gutman tells us. Reporter: Tonight vivian is locked up in a county jail, the same jail as her 14-year-old daughter. I can tell you this, ladies and gentlemen, once again, i repeated it earlier in the week, the apple doesn't fall far from the tree. Reporter: Vosburg's daughter was charged this week along with a 12-year-old. The 14-year-old tormented this girl before she committed suicide last month. She was only 12. Perhaps the greatest insult came on facebook after her death. She allegedly wrote, yes, I know I bullied rebecca and she killed herself, but I don't give a -- in an interview, vosburg said her child wasn't a bully and never made the post. Every day you check the phone. Text messages, facebook? Everything. I would suggest to you, after looking at this video online, that vivian does not monitor the facebook. Reporter: Vosburg's husband said violence never happens in their home. The sheriff told me he was vest gating the parents. How much is this about the parents and how much is it about their kids? I hold the parents equally responsible. They are the adults. They are the parents. Reporter: Vosburg faces two counts of child abuse and four counts of child neglect. Because there was so many children in the room at that time, now, if she's convicted on all charges, she could face 30 years in prison.
